4-Digit Multiplication -- the proof is in the Montessori pudding!
Rocky is just now 8, and though she should be in the 2nd grade (year 3) if she went to school, she's in the 3rd grade (Year 4) Shillermath book. Rocky, the (not always) model student! Some of you may be thinking: "Oh, that's all right for you! She obviously has the genes/the talent/the instruction/(insert explanation here", but let me tell you, this is the most free-wheeling, doll-playing, coloring-book-addicted child I've ever seen. Yet, somehow, she picks things up. (I've just deleted the phrase "just by listening", because I'm not sure she even does it by listening -- when we do our read-alouds, she can rarely muster up a decent narration beyond "There was this guy ... and he rode his chariot to this other guy ... and he shot him in the head or something" -- Rocky's version of 2 Kings 9 where Jehu shoots Joram in the back with an arrow. Kudos to her -- there WERE two guys, and there WAS a chariot, and someone did some shooting.)...
